I would say the answer is D, since the sample only shows that customers on Mondays were surveyed, and says nothing about other customers on different days.
X = 2y - 12....so sub 2y - 12 in for x in the other equation
3x + 4y = 14
3(2y - 12) + 4y = 14
6y - 36 + 4y = 14
6y + 4y = 14 + 36
10y = 50
y = 50/10
y = 5
x = 2y - 12
x = 2(5) - 12
x = 10 - 12
x = -2
solution is (-2,5) <==
